Controlling Red Rice with Mesotrione

ABSTRACT

Methods for controlling weeds in a crop, comprising applying to the weeds a herbicidally effective amount of a composition comprising a p-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor are presented.

The presently disclosed subject matter relates to methods for controlling weeds using compositions containing p-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors, specifically, mesotrione.

BACKGROUND

One of the more preferred methods of controlling weeds in crops involves the post-emergent control of weeds wherein herbicide(s) are applied after the crop in question has emerged from the soil. Post-emergent control is desirable as it requires the application of herbicide only where an infestation of weeds is present. In contrast, pre-emergent control requires the application of herbicide early in the growing season before most weeds have germinated, with the result that such chemicals must be employed throughout a field even if they would ultimately not be needed.

p-Hydroxyphenylpyruvate dioxygenase (HPPD) is an enzyme found in both plants and animals, which catalyzes the catabolism of the amino acids phenylalanine and tyrosine. Inhibition of this enzyme has profound effects on plants, affecting the formation of homogentisic acid which is a key precursor for the biosynthesis of both tocopherols (vitamin E) and plastoquinone, a critical co-factor in the formation of carotenoids, which protect chlorophyll in plants from being destroyed by sunlight. Mesotrione is a herbicide that works by inhibiting HPPD.

Red rice is a weed that infests cultivated rice growing areas in the United States. It is a wild rice type that competes with cultivated rice for nutrients, water, and space. Presently, there is a need for a method for controlling the growth of red rice without harming the cultivated rice.

SUMMARY

That need is fulfilled by the present disclosure. The present document discloses methods for controlling weeds in a crop, including methods for using mesotrione to kill the weed red rice without causing high injury to cultivated rice crops. In one aspect, this method includes applying to the weeds a herbicidally effective amount of a composition comprising a p-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor.

In one embodiment, the HPPD inhibitor is selected from mesotrione, sulcotrione, nitisinine, tembotrione, topramezone, fenquinotrione, ketospiradox and tefuryltrione. In a preferred embodiment, the HPPD inhibitor is mesotrione.

In another embodiment, the weeds are one or more selected from a group that includes red rice, broadleaf signalgrass, barnyardgrass, large crabgrass, hemp sesbania, yellow nutsedge, and benghal dayflower. In a preferred embodiment, the weed is red rice.

In another embodiment, the crop is rice. In another embodiment, the mesotrione is applied at a rate of from 3 to 200 g ai/ha. In a preferred embodiment, the mesotrione is applied at a rate of 3, 6, 12, 12.5, 25, 37.5, 50, 62.5, 75, 87.5, 100, or 200 g ai/ha.

DETAILED DESCRIPTION Definitions

As used in this application and unless otherwise indicated the term “herbicide” refers to a compositional mixture that is produced, sold, or used in a field in order to kill or otherwise inhibit unwanted plants such as, but not limited to, deleterious or annoying weeds, broadleaf plants, grasses, and sedges; and can be used for crop protection, edifice protection or turf protection. The term “herbicide” includes the end-use herbicidal product. This composition can be a pure compound, a solution of chemical compounds, a mixture of chemical compounds, an emulsion, a suspension, a solid-liquid mixture, or a liquid-liquid mixture. The term “herbicide” also refers to the product that passes through the commercial channels from the manufacturer to the ultimate end user who can either apply the herbicide to the affected field as sold, or mix it with other excipients.

The term “weed” means and includes any plant which grows where not wanted.

The term “herbicidally effective amount” means an amount necessary to produce an observable herbicidal effect on unwanted plant growth, including one or more of the effects of necrosis, death, growth inhibition, reproduction inhibition, inhibition of proliferation, and removal, destruction, or otherwise diminishing the occurrence and activity of unwanted plants. The term “herbicidally active ingredient” means the active ingredient in the herbicide that causes the herbicide to prevent, destroy, repel or mitigate any weed. Other ingredients of the herbicide that are not herbicidally active ingredients are excipients that aid in forming, storing, or delivering herbicidally active ingredient to the target. Examples of excipients in the present embodiment include, without limitation, an organic liquid in which herbicidally active ingredient is dissolved, a polyurea shell, a water-soluble polymer, and one or more salts.

The definition of the term “herbicidal composition” refers to a herbicide, and in addition, to any composition that comprises a herbicidally active ingredient. This composition can be a solution or a mixture. Further, the definition of the term “herbicidal composition” also refers to a product intended for use in manufacturing, or any product intended for formulation or repackaging into other agricultural products.

“HPPD inhibitor” means a compound that inhibits para-hydroxyphenyl-pyruvate dioxygenase.

The compositions included in the methods of the present disclosure can be in any conventional agriculturally useful form, for example, in the form of a twin pack, or in a ready-to-use formulation, or in the form of a tank mix. Additionally, the active compounds can be supplied (either separately or pre-mixed) in any appropriate formulation type, for example an emulsion concentrate (EC), a suspension concentrate (SC), a suspo-emulsion (SE), a capsule suspension (CS), a water dispersible granule (WG), an emulsifiable granule (EG), a water in oil emulsion (EO), an oil in water emulsion (EW), a micro-emulsion (ME), an oil dispersion (OD), an oil miscible flowable (OF), an oil miscible liquid (OL), a soluble concentrate (SL), an ultra-low volume suspension (SU), an ultra-low volume liquid (UL), a dispersible concentrate (DC), a wettable powder (WP) or any other technically feasible formulation in combination with agriculturally acceptable adjuvants.

The compositions and tank mixes of the present disclosure are useful for the control of susceptible weed species in crops such as rice. In one embodiment, the susceptible weeds include one or more selected from a group that includes waterhemp, lambsquarters, velvetleaf, palmer amaranth, pigweed, morning glory, cocklebur, ragweed, broadleaf signalgrass, foxtail, crabgrass, volunteer soybean, nutsedge, Egyptian crowfoot grass, fumitory, denticulate medick, lesser swine cress, brown beetle grass, jungle grass, tendla, false amaranth, common purslane, field bindweed, red rice, barnyardgrass, large crabgrass, hemp sesbania, yellow nutsedge, and benghal dayflower. In a preferred embodiment, the susceptible weed is red rice.

Rates of application of the composition will vary according to prevailing conditions such as targeted weeds, degree of infestation, weather conditions, soil conditions, crop species, mode of application, and application time. Compositions containing an HPPD inhibitor can be applied as sprays, such as water-dispersible concentrates, wettable powders, or water-dispersible granules. In one embodiment, the rate of application for active ingredient (“ai”) (e.g. an HPPD inhibitor, such as mesotrione) is from about 3 to 200 g ai/ha. In a preferred embodiment, the mesotrione is applied at a rate of 3, 6, 12, 12.5, 25, 37.5, 50, 62.5, 75, 87.5, 100, or 200 g ai/ha.

Examples Example #1—the Application of Mesotrione to Flooded and Dryland Rice

In greenhouse studies, mesotrione (Callisto®Herbicide available from Syngenta Crop Protection, 40% active ingredient, “AI” or “ai”) was applied at 12.5, 25, 37.5, 50, 62.5, 75, 87.5, or 100 g ai/ha, while clomazone (Command® 3 ME Herbicide available from FMC Corporation, 31.4% AI) was applied at 200 g ai/ha as a commercial standard.

Pre-Emergent Evaluation on Flooded Rice: Rice (Oryza sativa) crop varieties (‘Cybonet’, ‘Jupiter’, and ‘Taggart’) and red rice (Oryza sativa) were planted in 6 inch plastic pots containing sterile top soil. Eight to ten seeds of each species were seeded at 12 o'clock, 3 o'clock, 6 o'clock or 9 o'clock around the pot. The pots were watered after planting. Test solutions were prepared by diluting Callisto® Herbicide with water to the appropriate test rate. The test solutions were applied using a compressed air track spray chamber at 30 gallons per acre using a Teejet 8001E nozzle at 40 PSI, three replicates per test rate. After treatment, the pots were watered lightly and transferred to trays in a greenhouse. After the plants were two inches in height the trays were flooded with water and maintained as such for 14 days. The trays were emptied of water and the pots were maintained by regular watering for 4 more days. At 14, 21 and 28 days after treatment (DAT) the plants were evaluated versus untreated control pots containing the same rice and weeds using a scale of 0% (no control) to 100% (complete plant death).

Pre-Emergent Evaluation on Dryland Rice:

Rice (Oryza sativa) was planted in 6″ by 10″ fiber flats filled with sterile top soil. Five rows were made in each flat and the three rice varieties (‘Cybonet’, ‘Jupiter’, and ‘Taggart’) were planted in the center 3 rows and a row of red rice (Oryza sativa) was planted on either end of the flat. The flats were watered after planting. After application flats were placed in the greenhouse and lightly watered. Treatments of Callisto® Herbicide were applied using compressed air in a track spray chamber at 30 GPA using a TeeJet 8001E nozzle at 40 PSI). The flats were moved to a greenhouse and watered and fertilized routinely. Studies were conducted using randomized complete block design with four replications. In both studies, visual percent red rice control and rice injury were recorded at 14, 21, and 28 days after treatment (DAT), using a scale of 0 (no control/injury) to 100 (complete plant death).

PRE Flooded Rice—

As can be seen from the data in Tables 1 through 3, Callisto® Herbicide unexpectedly controlled red rice at all rates (≧90% control) and was safe (10% or less injury) on ‘Cybonet’, ‘Jupiter’ and ‘Taggart’ varieties of rice at application rates up to 50 g ai/ha. Clomazone at 200 g ai/ha injured all varieties of rice and failed to control red rice.

PRE Dryland Rice—

Similar as can be seen from the data in Tables 4 through 6, to flooded rice, Callisto® Herbicide unexpectedly controlled red rice at rates up to 62.5 g ai/ha without affecting the safety of ‘Cybonet’ and ‘Jupiter’ varieties of rice, and at rates up to 50 g ai/ha for ‘Taggart” variety. Clomazone at 200 g ai/ha injured all varieties of rice and failed to control red rice.

Example #2—Pre-Emergent Weed Control Using Mesotrione in Direct-Seeded Flooded Rice

Seeds of crops, rice (Taggart and Wells varieties) and weeds, yellow nutsedge (Cyperus esculentus), barnyardgrass (Echinochloa crus-galli), large crabgrass (Digitaria sanguinalis), hemp sesbania (Sesbania herbacea), Benghal dayflower (Commelina benghalensis), red rice (Oryza sativa) and broadleaf signalgrass (Urochloa platyphylla) were planted in two gallon pots containing top soil. Each pot was watered well before the application of mesotrione (Callisto® Herbicide from Syngenta Crop Protection). Test solutions were prepared by diluting Callisto® Herbicide with water to the appropriate test rate. The test solutions were applied using a compressed air track spray chamber at 30 gallons per acre using a Teejet 8001E nozzle at 40 PSI, three replicates per test rate. After treatment, the pots were watered lightly and transferred to trays in a greenhouse. After ten days the trays were flooded with water and maintained as such for 14 days. The trays were emptied of water and the pots were maintained by regular watering for 4 more days. At 28 days after treatment the plants were evaluated versus untreated control pots containing the same rice and weeds using a scale of 0% (no control) to 100% (complete plant death). The average percent weed control and average percent of rice injury is summarized in Table 7 below.
